Impact of Mulch and Irrigation Schedules on Yield and Quality of Spring Sunflower in Tarai Region of Northern India

The field experiment was carried out at Forage Block, Instructional Dairy Farm, Nagla, G. B. Pant University of Agriculture & Technology, Pantnagar (Uttarakhand) in spring 2019 to, study the effect mulches and irrigation schedules on productivity water use efficiency sunflower (Helianthus annuus L.) Mollisols Uttarakhand (India). consisted 03 levels i.e., control (no mulch), straw mulch @ 6t/ha polythene (black) main plot 04 critical stages (button, flowering, seed filling stage), 0.8, 1.0 1.2 IW/CPE ratios subplots, laid split-plot design with three replications. Under application mulch, significant output observed that statistically comparable to mulch. yield found be 4.6% 18.5% greater than under control, respectively. produced significantly higher stover non-significant Polythene 8.10% 10.4 % Sunflower differed among schedules. Irrigation applied highest 5.4, 11.1, 14.8% scheduled 1.0, 0.8 IW/CPE, stages, Among schedules, recorded 5.8, 8.0, 10.8% ratio ratio, Overall, it is highlighted gives quality parameters. give yield, protein content oil content.
